Hi guys, I have been working on cars since I was a teenager, but I have very little experience on this older stuff. I don't even know exactly what High Energy Ignition even really means. Wikipedia has this to say:

"High energy ignition, also known as H.E.I., is an electronic ignition system designed by Delco-Remy Division of General Motors and introduced by General Motors around May 1974 on most GM engines. It was used on all engines in 1975 through the mid-1980"

My truck is a 67 C10, it has a 350ci motor that I am told is out of a 1974 Corvette.

So it sounds like it must be a HEI because it says Delco-Remy and is supposed to be out of a 1974. Is this a good distributor? Is it something I might want to upgrade? Does anyone want to share their wisdom with me?
